Have you ever wondered about Uranus? Uranus is the seventh planet from the Sun. It is 1,787,860,000 miles from the Sun. Uranus is the farthest planet that can been seen without a telescope. It takes Uranus 84 years to orbit its axis. Uranus is fourteen times bigger than the Earth with 51,000 km of diameter. Uranus appears with blue and green clouds on the surface. It is made of rock and water.
Uranus is not suitable for human beings. The temperature of its atmosphere is -355 degrees F. The temperature increases as it moves toward the core. The rocky core has the temperature of 4200 degrees F. Besides its atmosphere is composed 83% of hydrogen, 15% of helium and 2% of methane. Also the air pressure is 1.3 times at the surface of the Earth. The gravity at the Uranus is less than the earth, which is about 95% of Earth's gravity. What makes Uranus impossible for people to live there is because of its low temperature at the surface, and its lack of oxygen. That's why we can't survive on Uranus.
This planet was first discovered in 1871, the time during American Revolution war, by a British astronomer William Herschel. It was then the Uranus was recognized as poart of our Solar System. Five moons was also discovered at that time. Equally important Uranus's ring system was discovered in 1997. On January 24, 1986, U.S space craft voyager orbited Uranus in the distance with 50,000 miles. Even Voyager was't able to get very close to Uranus due to is blue and green coulds, Voyager made significant discoveries about Uranus. It found ten new moons, and furthermore discovered that the particles of its ring system was made of ice.
As been said, Uranus is a very special planet. First being the most distant planet that is visible without a telescope, Uranus appears to be blueishh and greenish. Second, it is smaller than our planet earth. In addition, Uranus is not a suitable habitate for human beings due ot his extreme temaperature. airpressure, and lack of pressure. Of course the discovery of Uranus and its mooms and rings help us to have a clear picture of this unique planet. I wish I can see Uranus during my fieldtrip to planetarium.
